UNITED STATES PATENT OFFICE.

JOHN B. CHRISTIAN AND A. BEELER, OF MOUNT CARROLL, ILLINOIS.

PUMP.

Specification of Letters Patent No. 28,544, dated April 12, 1859.

To all whom it 'may concern:

Be it known that we, JOHN B. CHRisTiAN and ABRAHAM BnnLnn, of Mount Carroll, in

the county of Carroll and State of Illinois, have invented a new and Improved Pump; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making` part of this specification, Fig nre l being` a central vertical section of the pump; Fig. Q, a side elevation thereof; Fig. 3, a horizontal section thereof, exhibiting parts indicated by letters of reference.

Like letters designate corresponding parts in all the figures.

The distinguishing feature of our improved pump is, the employment of three concentric cylinders G, H, I, one stationary, and the other two, sliding, each provided with a valve, and so arranged in connection with the other parts of the pump, as to pump a continuous stream of water, and to secure the advantages hereinafter specified.

The concentric cylinders are located in the water to be raised; the upper and inner one G. being stationary, and provided or connected with an air-chamber E, whence an elevating pipe I), conducts the water up to the spout A.

The upper, inner sliding cylinder H, tits accurately over the stationary cylinder Gr; and the lewer, outer sliding cylinder I, fits, in like manner. over the sliding cylinder I-I. These sliding cylinders are made to slide easily; and no packing is required between the cylinders. The three cylinders G, H, I, are respectively provided with valves m, 7L, of any suitable construction. The length of the cylinders is just sufficient to allow the required length of stroke to be given to the sliding cylinders, and to contain the valves.

The sliding cylinders are actuated by means of a lever C, at the top of the pump, from the opposite sides of whose fulcrum two rods a, c, extend downward nearly to the air-chamber E, where they are secured to yokes Z), b, from the ends of each of which a pair of rods-c, c, extends downward, em-

bracing the air-chamber and cylinders, and is secured to a flanch on the upper end of one of the sliding cylinders, one pair to the fianch 7, of the upper sliding cylinder, on opposite sides thereof, and the other pair, in like manner, to the flanch g, of the lower sliding cylinder. Thus, when one sliding cylinder is raised, the other is de ressed, and vice versa. Nuts and screws d, al, d, may be employed for attaching the rods c, c, c, c, to the yokes Z), b, in order to adjust the length of the rods to secure the proper positions of the cylinders. The mode of actuating the cylinders may be varied as desired; but the above is convenient and simple.

Since the sliding cylinders I-I, I, continually move in opposite directions, one or the other is continually raising water; and the motion of the water being thus continual, and constantly in one direction, the maximum amountof water, with a given force, may be raised with the pump. The construction is also simple, light, and cheap, and not liable to disarrangement. It is also exceedingly compact, combined with a large capacity, on account of the little space taken up by the thin cylinders; and for this rea` son, it is particularly applicable to the bored wells now much used in many parts of the country; since by this construction a smaller bore will sutlice for the well. There is no waste of water through perforations or slots in the cylinders, required in the ordinary kinds of piston force-pumps.

What we claim as our invention and desire to secure by Letters Patent, is-

The combination of two sliding cylinders with each other and with a third, stationary cylinder, arranged and operating substantially in the manner and for the purposes herein specified.
